摘要
本文着重分析了国内影响掘进机生产发展的主要因素，总结了国内掘进机掘错一体化、喷雾降尘设备随机化、完善液压系统和进一步提高中小型机可靠性等问题。并针对国外悬臂式掘进机的现状以及应用高科技使掘进机向着中重型化、矮型化、系列化和附件化的发展趋势进行了论述。
Stress is laid on analyais of main factors affectomg development of roadheaders in China, and problems existing in the fields of integration of drivage and bolting, randomized water -spraying dust suppression, improvement of hydraulic system and operating reliability of medium aed small-sized roadhead ers. Current status and developing trend in overseas countries and the efforts aimed at producing series medium heavy-duty and low-height roadheaders with hi-tech are also elaborated in detail.
